YII2中的多个where子句

Question

我有一个问题,如何使用条件WHERE在YII2中使用Closure类型Active记录查询.

这就是我想要实现的目标:

public function getUsers($limit = 10, $type = 1, $company_id = 0) { 
    return User::find()->where( function($query) use ($type, $company_id){       
                $query->where(['type' => $type]); 
                if($company_id != 0) { 
                   $query->andWhere(['company_id' => $company_id]); 
                } 
               })
            ->orderBy([ 'created_at'=> SORT_DESC, ]) 
            ->limit($limit); 
}

如果有人知道这个,请帮忙

无法弄清楚Closure的用途.您可以使用andFilterWhere()for company_idcondition,但是您应该将其设置为null作为默认值,因此如果未初始化company_id,则将忽略此条件:

public function getUsers($limit = 10, $type = 1, $company_id = null) { 
    return User::find()
            ->where(['type' => $type])
            ->andFilterWhere(['company_id' => $company_id])
            ->orderBy([ 'created_at'=> SORT_DESC ]) 
            ->limit($limit)
            ->all(); //probably you muiss it
}
